Terfamex: Phentermine Weight Loss Pills

Terfamex is a Mexican brand of phentermine weight loss pills. Available in both capsule and orally disintegrating tablet (ODT) form, this medication helps suppress appetite and boost energy so that patients can lose weight more quickly and easily. It is only sold under a doctor's prescription and should not be used for more than 12 weeks at a time.

Terfamex is currently available in Mexico, Venezuela, Peru, Colombia, Panama and Argentina.

What is Terfamex?

Terfamex is a Mexican brand of phentermine weight loss pills that is sold primarily in Latin America. It is a branded preparation of the popular prescription appetite suppressant, phentermine hydrochloride (phentermine HCL). This medication helps overweight patients eat less and move more to lose weight faster. The medicine works by suppressing appetite and giving users an extra boost of energy.

Phentermine HCL has a chemical structure similar to amphetamines. Given its strength and addictive potential, the compound is classified as a class IV controlled substance. As a result, Terfamex (phentermine) is a short-term medication and only available under a doctor’s prescription.

Who can take Terfamex?

This medication is an option for people with a body mass index (BMI) greater than 30, who are considered medically obese. It is also available for overweight patients with a BMI greater than 27 if the individual also struggles with a weight-related condition like type 2 diabetes or high blood pressure.

However, a patient’s level of obesity is not the only factor to consider. It is also important to asses why a patient is overweight, as well as their current health status, other medications and medical history. Phentermine (Terfamex), should only be used for the management of exogenous obesity. This is a type of adiposity caused by eating and drinking more calories than you burn on a day-to-day basis. If a person is overweight for another reason (e.g. thyroid problems or another medical condition), phentermine may not be the best option. Additionally, Terfamex (phentermine) should not be used in the presence of some medical conditions or in combination with some medications [1].

For this reason,a medical doctor is the only person who can determine if Terfamex is right for you.

Dosage

Terfamex is currently available in two different presentations and three different doses. At your prescribing appointment, your doctor will work with you to determine which dose and presentation is correct for you.

Always take this medication exactly as prescribed. NEVER take Terfamex at a higher dose or more often than prescribed. Taking more will not increase effectiveness and can be dangerous.

Terfamex 15mg

Fifteen milligrams is the lowest available dose of this medication. It is the only dose that is sold in both capsule and ODT form.

Terfamex 15 mg pills can be taken one or two times per day, depending on doctor’s orders. People who struggle with nighttime cravings or binging sometimes prefer to take two smaller doses of phentermine throughout the day (instead of one larger dose in the morning) so that the medication works later into the day. However, if you struggle with insomnia this may not be the best option.

Terfamex 30 mg

Terfamex 30 mg is the highest dose of Terfamex available in capsule form.

Terfamex 30 mg should only be taken once a day, usually early in the morning. The capsule should be swallowed whole with water and is typically taken on an empty stomach.

Terfamex 37.5 mg

37.5 mg is the highest daily dose of this medication, and it is only available as an ODT.

This dose should only be taken once a day, preferably in the early morning. Since it is an ODT, it can be taken with or without water. ODTs are a good option for people that have trouble swallowing capsules, but they tend to cost more than traditional capsules or tablets [2,3].

How To Take Terfamex

Since this is a prescription medicine, your doctor and pharmacist should give you clear directions for how to take your medication.

Given the medication’s addictive potential, as well as its progressive loss of efficacy, Terfamex should only be taken for 12 weeks at a time. The United States FDA only approved phentermine for this short course of treatment and research has not assessed the safety of taking the medication for longer periods of time [1].

If you and your doctor feel that you need more than three months of treatment to reach a healthy weight, your prescribing physician may choose to prescribe you multiple rounds of phentermine punctuated by regular breaks.

When to Take Terfamex

Your doctor will talk to you about specific dosing instructions to accommodate your individual schedule, but this medication is typically taken:

First thing in the morning (before breakfast), OR

1-2 hours after breakfast

Given the simulant properties of phentermine HCL, avoid taking you medication within 8 hours of bedtime. This should be easy if you are only taking one pill per day, but if you take 15 mg twice per day, make sure to take your second dose relatively early in the afternoon so that you are able to sleep at night.

Always take Terfamex EXACTLY as prescribed by your doctor. NEVER take phentermine more often or at a higher dosage than prescribed.

Terfamex Side Effects

Phentermine is a phenomenally effective weight loss medication, but it can also cause some serious side effects. While most patients experience only mild reactions – such as dry mouth, headache or insomnia – others are forced to deal with more severe effects.

Severe Side Effects

Symptoms of a severe reaction this medication include:

Chest pain

Trouble breathing

Fainting

Swelling of feet or lower legs

Difficulty in carrying-out day to day activities.

If you experience any of these side effects while taking Terfamex, seek immediate medical attention.

Other Considerations

While taking Terfamex, or before pursuing a prescription, keep the following factors in mind:

Terfamex and Alcohol

Phentermine is an “upper”, while alcohol is a “downer”. The combination of these conflicting effects increases the risk of cardiovascular and other side effects, like dizziness, racing heart and high blood pressure. Since both phentermine and alcohol affect each person differently, it proves risky and potentially dangerous to combine the two substances. Do NOT drink alcohol while taking this medication [4].

Terfamex and Other Medications

Terfamex interacts with many medications and supplements, so you should always clear any change in your pill routine with a medical professional. Your prescribing doctor especially needs to know if you currently take, or in the last two weeks have taken, a(n):

Terfamex and Birth Control

Just like any other medication, you should always check with your doctor before combining Terfamex and birth control pills. Some sources indicate that taking the two medications side-by-side can increase the risk of thrombosis, so it’s best to check with a doctor and pharmacist before combining Terfamex and birth control.

Still, there are countless options for birth control. Talk to your prescribing doctor, pharmacist and gynecologist about the best option for you.

Terfamex and Pregnancy

Phentermine is pregnancy category X. You should not take Terfamex if you are pregnant or trying to conceive. It’s not stated whether phentermine passes into the breast milk, so you should also avoid this medication if you are nursing or pumping milk [1,5].

Where to Buy Terfamex

A valid prescription can be filled at most major pharmacies.

This brand of phentermine is commonly available in:

Mexico

Venezuela

Peru

Colombia

Panama

Argentina

If you are interested in phentermine, speak to your doctor about a prescription. He or she will evaluate the appropriateness of this medication in your specific case and then assess whether this medication is right for you.

If you do not have a primary care doctor, or he/she does not prescribe phentermine, consider speaking with a physician at a weight loss clinic or another specialist that would be concerned about your weight (e.g. a gynecologist if you’re a woman).

Terfamex Without a Prescription

This medication is NOT available without a prescription.

Since the main ingredient (phentermine HCL) is a controlled substance, the distribution and sale of these prescription weight loss pills is tightly controlled. The only way to legally and safely buy Terfamex is to get a prescription from a trustworthy doctor and then fill it at your local pharmacy.

What if I can’t get a prescription?

If phentermine is not right for you, or if you can’t find a doctor to prescribe the medication, consider an over-the-counter alternative. Phen Caps is an all-natural weight loss supplement that suppresses appetite and boosts energy to help you lose weight faster.

In Comparison to Other Weight Loss Pills

Are you interested in prescription weight loss medications, but not sure if Terfamex is right for you? Here’s a comparison of this medication to some other medications and supplements on the market.

Terfamex vs. Acxion

These are two brands of phentermine weight loss pills available in Mexico. Both pills contain the same active ingredient and come in a variety of doses, but the presentations are different. Both brands produce capsules, but their other pills vary. Terfamex specializes with an ODT, while Acxion manufactures regular and extended-release tablets. The price of the brands is comparable for a 30-day supply of medication.

At your first appointment, you and your doctor can discuss which brand and form of phentermine is right for you.

Terfamex vs. Orlistat

Both are both prescription weight loss medications, but they contain different active ingredients. While Terfamex contains phentermine HCL, orlistat is actually the name of the active ingredient in a class of once-popular weight loss medications.

Phentermine helps patients lose weight by suppressing appetite and increasing energy. Orlistat, on the other hand, decreases fat absorption in your intestines [10]. It does not affect appetite or energy, so eating proper portions and staying active is left up to you and your willpower while taking orlistat.

Orlistat is legal in most countries, including many that have banned phentermine, and sold under various brand names including:

Andanza

Lindeza

Redustat

Orlistat MK

Xenical

Alli (OTC version; sold in US and UK)

Terfamex vs. Redotex

Terfamex contains phentermine HCL as its active ingredient, while Redotex relies on a cocktail of potentially-dangerous ingredients. This “Mexican Miracle Diet Drug” is made by Medix and promises impressive results, but actual reviews of the prescription-only medication are very mixed.

In fact, Redotex is banned in the USA due to safety concerns. The risky drug contains norpseudoephedrine, atropine sulfate, diazepam, aloin, and triiodothyronine.

Talk to your doctor about the benefits and risks of these pills before filling your prescription.
